Lua Programming Help Thread

ok. this is to ALL CODERS. i have seen a lot of code such as:

Code:

---

screen:print(100, 130, "blah", red)
screen:flip()

---

if you put this code:

Code:

---

screen.waitVblankStart()
screen.flip()
end

---

at the VERRRYYYY END of your codem you dont have to worry about screen:flip() for your ENTIRE CODE. it becomes much easier that way.

Umm...I'm having a slight problem. Is there any way to "pause" a loop? I ask this because I have an options menu that comes up whenever you press start, the only problem is that when it comes up, the player will keep moving while the menu is up. The menu actually has its own loop because of some stuff I added in there, but this still happens no matter what I do. Does anyone have any suggestions? Thanks guys.

Ive never done it but you could try this

while not pad:start() do
-- main loop --
end

if pad:start() then
--menu --
end

you could have a boolean:

Code:

---

pause = false

---

then:

Code:

---

if pause == false then
--the code for you character moving..etc
end

---

after:

Code:

---

if pad:start() and pause == false then
pause = true
end

---

and finally:

Code:

---

if pause == true then
--your menu code
end

if pad:start() and pause == true then
pause = false
end

---

try it out.

Yea, that's what I was planning on doing but I just wanted to know if there was a simple command I was missing so I wouldn't have to cater my whole game around the options menu.

Look

Code:

---

if true then
screen:blit(x1, y1, player2)
x1 = x1 + 2
end

if true and pause == true then

screen:blit(x0, y0, up2)
screen.flip()
screen.waitVblankStart(10)

screen:blit(x0, y0, up1)
screen.flip()
screen.waitVblankStart(10)

y0 = y0 - 2
end


if pad:up() then
pause = true
end

---

This is a better example.

picture "player2" will atomatically move right.
If i press Up, It will not move smooth and will start to skip some pixels

The good thing i liked about the "screen.waitVblankStart(1 0)" is that it makes picture "up1" and "up2" to keep changing atomatically.

The bad thing is that "screen.waitVblankStart(1 0)" Makes picture "player2" movement and the picture "up1" and "up2" movement not smooth and skipping some pixels.

My question is:
Is there a way to fix the bad thing :neutral: ?

Figured it out! Just go to View and uncheck Word Wrap. Then it works.
